11.7.1
The structured assembly function expands the structured assembly directives into predetermined
instructions and symbols, and performs no optimizations whatsoever. Thus the values that can be
specified as parameters to these directives are limited by the specifications of the instructions that
are generated. Furthermore, there are cases where inefficient code and/or unnecessary symbols
are generated.
1. Instruction Expansion
2. Symbol Expansion
The forms of structured assembly directives that involve testing condition codes may be
restricted by the statement that results from expansion of the directive.
Example:
.IF B (R0L<LT>#10)
.ENDI
The .IF directive is expanded to CMP instruction.
However, this .IF directive results in CMP R0L,#10, and this causes an error. To avoid this,
the program must be written in the following way:
.IF B (#10<LT>R0L)
.ENDI
Structured assembly statements generate symbols in the forms shown below.
.IF
.SWITCH
.FOR[U]
.WHILE
.REPEAT
Accordingly, such symbols are not available to the user.
MOV.W R1,R2
MOV.W R1,R2
